Gold touched $584 and rebound

Gold has been fluctuating around $600-$650 these few months.
Past weeks has been around $610-$630, then dropped suddenly from $640 to $584 in 3-4 days' time.
$580 looks like a support and it stopped dropping at $584 yesterday and formed a rebound to test $600 again. Now it was trading at $592.
Personally I guess $580 would be a good enough short term supporting line. In the long term I still think Gold's future would be bright.
